Help with grass ID?

Hey team,

I have a perennial polyculture plot that I hunt over.  I had a cool season grain planted to this early in spring, and then it got flooded out, and I lost all my cereals.  Then this grass filled in.  Can anyone ID this?  This is in a lower ground soil, and in zone 3 in northern MN.  

My first thought was red top, but I am not great with grasses. Mostly I wanted to recommend the website minnesotawildflowers.info for plant id. There is a section for grasses. I’m in Wisconsin but from Minnesota & I use the site all the time to help me identify wildflowers and other plants I come across.
